​​Introduction to FGT_60D-v500-build0179-FORTINET-5.0.2.out Software​​

This firmware package (build 0179) represents an essential legacy update for FortiGate 60D series firewalls running FortiOS 5.0.2, originally released to address critical security vulnerabilities and optimize network performance for small-to-medium business deployments. Designed as a maintenance release, it enhances baseline firewall functionalities including stateful packet inspection, IPSec VPN throughput, and web filtering capabilities.

Compatible exclusively with FortiGate 60D hardware appliances, this build belongs to FortiOS 5.0.x branch – a foundational release series that established modern Unified Threat Management (UTM) features. While official release notes are archived, historical security bulletins confirm its role in resolving CVE-2014-8638 (SSL-VPN session hijack vulnerability) and improving DHCP server stability.
